Not with just one mv command, but almost as simple,

  for f in *[0-9] ; do mv $f $f.html ; done

If you have hundreds of files, or if there are any unusual filenames
(such as containing spaces or nonprintable characters), a more
robust but longer command is (on two lines here for readability),

  find . -type f -name '*[0-9]' -print0 | \
    xargs -0 --replace mv -- {} {}.html

The "0" in -print0 and -0 is a digit-zero, not a letter Oh.

Note, the *[0-9] pattern is there to match only those filenames that
end in a digit (as in your example), so it doesn't match any other
files.
